Vega AHRS-1 / AHRS-3 / MAG-1 Operating Manual Page 7 3.3.4 Heading stability issues You may find short term fluctuations of the heading occurring. These tend to be very small and are typically less than one degree. This could still cause the heading to fluctuate occasionally by a single degree. These fluctuations occur naturally in the earth’s magnetic field and can also be caused by nearby electrical equipment such as radios, lamps, electronic in -... -

- Page 10 Vega AHRS-1 / AHRS-3 / MAG-1 Operating Manual Page 10 Slip Sense: Select if you want the slip to have a high sensitivity or a low sensitivity setting. Slip Zero: This function allows you to set your slip indicator to exactly zero even if your aircraft tends to fly slightly wing down. The procedure is to place the aircraft in a stable, straight and level attitude during calm flight conditions and then select this function.
- Page 11 After you activate this procedure it takes about 30 seconds to complete it. Keep the aircraft perfectly still during this operation. CAN TX AHRS (AHRS-3 only): Select “ON” to output the MGL Avionics SP7 CAN bus messages. This gives the AHRS-3 the ability to emulate the MGL Avionics SP7 sensor package.
